            </p>
            <p>Notes.</p>
            <p> Sticta amboroensis forms an isolated lineage not far from other green algal species, such as  S. pulmonarioides B. Moncada &amp; Coca and  S. subscrobiculata (Nyl.) Gyeln. These species are characterised by a similar morphology, but clearly distinguished phylogenetically. In  S. subscrobiculata , the lobes are sparsely branched and pleurotomous and the marginal cilia are sparse to absent, although a cilia-like extension of the lower tomentum is usually visible (Moncada 2012). In the case of  S. pulmonarioides , thallus is smaller, up to 15 cm in diam., with sparse, mainly submarginal apothecia. In addition, the lower tomentum is sparse over the entire lower surface (Moncada et al. 2013a). </p>

            <p>Habitat and distribution.</p>
            <p> Sticta aymara is known only from the type locality in the Department La Paz, at an altitude of 1989 m. </p>
            <p>Etymology.</p>
            <p>The name refers the Aymara people in the Andes and Altiplano regions of South America who coined the term Yungas.</p>
            <p>Notes.</p>
            <p> Although this new taxon is known from a single collection only, we decided to describe it formally, as the material is well-developed and phylogenetically distinctive, shown by two sequences generated from different pieces of the specimen.  Sticta aymara forms a sister clade with the also newly-described  S. narinioana from Colombia (see below). Both taxa produce isidia, but in  S. narinioana , they are concentrated along the thallus margins and horizontally orientated, while in  S. aymara , they are laminal and upright. Moreover, sparse, submarginal apothecia, absent in  S. aymara , were observed in  S. narinioana . Cilia are absent in both taxa, but in  S. narinioana , the white tomentum projects beyond the edge of the lobes and resembles cilia. The two species also differ in the abundance of cyphellae, which are more densely arranged in  S. narinioana . </p>
            <p> The presence of isidia is also characteristic for  S. isidiokunthii B. Moncada &amp;  Lücking and  S. weigelii , amongst other similar species (Moncada 2012). However, isidia in these species are mainly marginal and differ in colour. In  S. aymara the isidia are grey, in  S. isidiokunthii , greenish-brown to brown and in  S. weigelii , blackish-brown. Moreover, the latter taxa are characterised by thalli larger than  S. aymara , up to 10-15 cm in diam. Differences were also observed in the structure and colour of the lower surface. In  S. isidiokunthii , it is uneven, beige to dark brown, while in  S. weigelii , it is smooth to undulate, beige to red-brown (Moncada 2012; Moncada and  Lücking 2012; Ossowska 2021). Additionally,  S. isidiokunthii also produces laminal apothecia (Moncada and  Lücking 2012). The medulla of both  S. isidiokunthii and  S. weigelii reacts with K, while in  S. aymara , it is K negative. </p>
            <p> The small size of the thalli, the presence of isidia and the absence of apothecia is also characteristic of  S. viviana A.  Suárez &amp;  Lücking . However, this taxon has a dark brown, scrobiculate to faveolate upper surface with cream-coloured maculae. Furthermore, the lower part is rugose to undulating, rather than ridged-veined as in  S. aymara . The medulla of  S. viviana is K+ orange-yellow and the cyphellae are K+ yellow. The latter species is known from Colombia and Costa Rica (Moncada 2012;  Suárez and  Lücking 2013; Moncada et al., unpub.).  Sticta aymara and  S. viviana are phylogenetically only distantly related (Fig. 1; Suppl. material 3: Fig. S1). </p>

            <p>Notes.</p>
            <p> Sticta bicellulata is similar to  S. pseudoimpressula (another species described below), but the main discriminating character in  S. bicellulata is the septation of the ascospores, which are predominantly bicellular (only very few are 3-septate whereas in  S. pseudoimpressula , only young ascospores are bicellular. Both taxa have irregular to suborbicular thalli, with laciniate to flabellate lobes, but the lobe apices in  S. bicellulata are obtuse to truncate vs. orbicular in  S. pseudoimpressula . Furthermore,  S. bicellulata has a paler upper surface than  S. pseudoimpressula . In both species, marginal cilia are present, but in  S. bicellulata , they are agglutinated, white to golden brown vs. fasciculated, light brown to golden brown in  S. pseudoimpressula . Apothecia in  S. bicellulata are sparse in contrast to the abundant apothecia in  S. pseudoimpressula . They also differ in the colour of the disc, which in both species is covered by a pruina. The margin and epihymenium react with K in both taxa, but in  S. bicellulata the reaction is K+ violet and in  S. pseudoimpressula K+ carmine-red, suggesting the presence of different anthraquinones. The lower surface in both species is uneven, but in  S. bicellulata , the tomentum is thick, becoming thinner towards the margin and a secondary tomentum is absent. Conversely, in  S. pseudoimpressula , the primary tomentum is consistently thick and long, with a secondary tomentum present and with rhizines. The cyphellae in these two taxa are similar in shape, but in  S. bicellulata , their margins are raised and involuted. </p>
            <p> Remarkably, the taxa form a sister group relationship, denoting the presence of apothecial anthraquinones as a synapormorphy, although apparently, the two species diverged to the point that the anthraquinones are of a different nature, as indicated by their different K+ reaction. This character appears to be rare in  Sticta , but may also have been overlooked, as it is only obvious in a close-up of the apothecium. </p>
            <p> The clade formed by  Sticta bicellulata and  S. pseudoimpressula is closely related to  S. sylvatica and  S. peltigerella (Fig. 1; Suppl. material 3: Fig. S1). The latter two produce numerous isidia distributed over the entire surface of the thalli (Moncada 2012).  Sticta sylvatica is widespread, occurring in Europe, North and South America (Hodkinson et al. 2014), whereas  S. peltigerella appears to be a Colombian endemic (Moncada 2012). </p>

            <p>Habitat and distribution.</p>
            <p> Sticta carrascoensis was collected at a single locality in the Parque Nacional Carrasco in the Department Cochabamba, at an altitude of 3283 m. The specimen grew on the bark of a tree in  Podocarpus-Polylepis forest. </p>
            <p>Etymology.</p>
            <p>The name refers the type locality.</p>
            <p>Notes.</p>
            <p> Sticta carrascoensis is phylogenetically close to  S. andina , although this relationship is not supported (Fig. 1; Suppl. material 3: Fig. S1). The latter differs by its cyanobacterial photobiont and the formation of isidia and/or phyllidia, not observed in  S. carrascoensis . The thalli in  S. andina are smaller (up to 15 cm in diam.), the margins of the lobes are sparsely covered by cilia and the medulla is white to cream, sometimes with yellowish patches and reacts K+ yellow (Moncada et al. 2021a). In  S. carrascoensis , the medulla is distinctly yellow and reacts K+ lemon-yellow.  Sticta andina is widespread in South America and, so far, has been confirmed from numerous localities from Brazil, Colombia and Ecuador and also from Costa Rica, Mexico and in Hawaii (Moncada et al. 2014a, b, 2020; Widhelm et al. 2018). Thus far, only one collection of  S. carrascoensis is known, but it is well-developed and phylogenetically unique, with no close supported relative. </p>

            <p>Habitat and distribution.</p>
            <p> Sticta catharinae is known only from the type locality in Yungas forest in the Department La Paz. </p>
            <p>Etymology.</p>
            <p> The new species is named to honour our late friend and teacher, Polish botanist Dr Katarzyna  Żółkoś , for her contributions to the conservation of nature. </p>
            <p>Notes.</p>
            <p> Sticta catharinae is the only species amongst those newly described here that is characterised by the presence of a stipe supporting the thallus. Morphologically, this taxon is similar to  S. aff. caliginosa D. J. Galloway and the cyanomorph of  S. neopulmonarioides B. Moncada &amp; Coca, which share the stipe and the palmate thallus. However, in  S. aff. caliginosa and  S. neopulmonarioides , no apothecia are known, whereas vegetative propagules in the form of isidia or phyllidia and lobules are present (Galloway 1997; Moncada 2012; Moncada et al. 2013a). In addition, these taxa differ in the shape of the lobes and the presence of marginal cilia. In  S. aff. caliginosa , the lobes are ligulate to flabellate, with their apices rounded to obtuse and with cilia being sparse to absent (Moncada 2012). In contrast,  S. neopulmonarioides has flabellate lobes with irregular apices, without cilia (Moncada et al. 2013a).  Sticta neopulmonarioides is widely distributed in Colombia, while  S. aff. caliginosa is a rare taxon in that country (Moncada 2012; Moncada et al. 2013a, 2014b). </p>
            <p> The new species is closely related to  S. fuliginoides (Fig. 1; Suppl. material 3: Fig. S1), a morphologically disparate taxon with broad lobes producing laminal isidia (Magain and  Sérusiaux 2015). It is also phylogenetically quite distinctive from the latter, with a total of 16 substitutions and nine indels in the ITS (Suppl. material 2: File S1), warranting its formal description, based on a single collection only. </p>

            <p> Sticta narinioana is known as epiphyte from two localities of well-preserved (sub-)andine forest in southern Colombia. </p>
            <p>Etymology.</p>
            <p> The epithet honours Antonio Amador  José Nariño (y  Álvarez del Casal) (1765-1823), one of the critical architects of the independence of Colombia and after whom the Department of  Nariño was named. </p>

Both taxa are cyanobacterial, isidiate species, but  S. aymara has largely laminal isidia and the lower tomentum is not projecting to resemble cilia. Additionally, the cyphellae are less densely arranged and smaller. </p>

            <p>Notes.</p>
            <p> Sticta pseudoimpressula is similar to  S. impressula (Nyl.) Zahlbr. Both species have a pitted to scrobiculate or rugose upper surface with abundant, laminal apothecia and the lobe margins with abundant, light brown cilia. The tomentum is dense to the margin in the latter (Moncada 2012). However, the two species are not closely related phylogenetically (Fig. 1; Suppl. material 3: Fig. S1):  Sticta impressula is clustered in a neighbouring clade with  S. brevior B. Moncada &amp;  Lücking and  S. isidiokunthii . In contrast,  S. pseudoimpressula shares a common ancestor with  S. bicellulata ,  S. peltigerella and  S. sylvatica . The differences between  S. pseudoimpressula and  S. bicellulata are discussed under the latter. </p>
            <p> The morphological features that distinguish  S. pseudoimpressula from  S. impressula are the moderately-branched thalli and the laciniate to flabellate lobes. The apothecia in  S. pseudoimpressula are often imbricately arranged and grouped and produced orange-yellow pruina along the disc margins and reacts K+ carmine-red. A secondary tomentum is present in  S. pseudoimpressula , but absent in  S. impressula . In addition, the cyphellae in  S. impressula are rounded to angular and urceolate with a wide pore, erumpent to suprasessile and the margins raised to involute. The latter taxon is widely distributed in Colombia, where it grows at elevations between 1500 and 3800 m (Moncada 2012; Moncada et al. 2014b). </p>
            <p> At first sight,  S. pseudoimpressula can also be confused with  S. brevior , but that taxon has smaller thalli with abundant apothecia, tomentose margins and the lower surface is undulating, creamy white to light brown (Moncada 2012; Moncada et al. 2013b).  Sticta brevior is known from Colombia (Moncada et al. 2013b, 2014b). </p>
